Bricsys Releases New LGS 2D and 3D Constraint Solvers

By DE Editors

Bricsys announced releases 7.0 of its LGS 2D and 6.0 of its LGS 3D constraint solver technology components used by developers of engineering application to implement parametric design functions for end users.

Bricsys acquired the intellectual property rights of LGS 2D and 3D from LEDAS in October 2011.

Version 7.0 of LGS 2D constraint solver contains several improvements in processing curve objects. It supports a wide range of curve objects,  including analytic curves (circles, ellipses, NURBS) and user-defined parametric curves. Version 7.0 also introduces a new function for evaluation of points on curves, tangent and curvature vectors for an analytic curve. Each constraint with curves uses help parameters to specify the parametric value of a point on a curve. The values of help parameters are computed automatically when a constraint is created.

Version 6.0 of LGS 3D introduces new functions aimed at supporting variational direct modeling applications. Users of such applications often move or rotate interactively one or more objects. LGS 3D is able to support this end-user operation by finding the transformations,  which do not violate constraints imposed on the objects. It also supports so-called extended transformations, which may include the changes of parameters (radii).

With version 6.0 it is possible to select pre-defined special positions for some tangency constraints. For example, a tangency between a torus and a plane may also assume that their axes are parallel (in that case,  the torus will tangent to the plane at any point along their common circle). Other predefined cases are for tangency between two torus (their axes are concentric).
